TOOTH- BRUSH.

:sPECIFICATION formingpart of Letters Patent No. 715,263, dated December9, 1902.

Application filed April 1, 1901.

To all whom, it may concern:

Be it known that I, ALBERT HAUSSMANN, a citizen of the United States,and a resident of Fond du Lac, in the county of Fond du Lac and State ofWVisconsin, have invented certain new and useful Improvements in Tooth-Brushes; and I do hereby declare that the followingisa full, clear, andexact description thereof. I

My invention relates to toothbrushes designed to brush the outer andinner surfaces of the teeth at the same time; and it consists in certainpeculiarities of construction and combination of parts, as will befullyset forth hereinafter in connection with the accompanying drawingsand subsequently claimed.

In the said drawings, Figure l is a front elevation of a tooth-brushembodying my invention, and Fig. 2 is a side elevation of the same.

Referring to the drawings, a represents the handle proper of the devicemade of any suitable materialsuch as bone, ivory, wood, metal, hardrubber, or other composition and secured thereto, as by pins, screws, orrivets Z) Z), are the shanks c 0, preferably flat strips of springmetal, of the brush-holders d 61, said shanks 0 beyond the end of thehandle ct being curved outwardly in opposite directions, and thencerearwardly and finally forwardly, as shown at e, and permanentlysecured, as by soldering or otherwise, to the brush-holders d.

The brush-holders d are preferably formed of flat metallic plates havingspring-tongues ff projecting from their upper, lower, and side edges, asshown, and curved or inwardly inclined, so as to securely hold thebrushbacks g, which are held in place by being slipped or snapped pastsaid tongues. The edges of the brush-backs are suitably curved orinclined for engagement with said correspondingly-bent tongues, and theouter or opposed faces of said brush-backs are each further preferablycurved on the arc of an ellipse and provided with any suitable brushingdevices, such as the rows of bristles h h shown.

With my device should the bristles or other bushing material become wornout the brush- Serial No. 53,75 2. (No model.)

backs can be removed and replaced by new brushes or brush-backs may beprovided in interchangeable series having brushes of different degreesof stiffness or softness to he used as required, one handle and pair ofspring-shanks serving for any of the same, this being a matter ofconsiderable advantage, as where a silver or other expensive handle isemployed.

The opposing pair of brushes are arranged in longitudintal planesslightly oblique to the longitudinal plane of the handle, and the endsof the shanks 0 beyond the handle dare outwardly curved in oppositedirections, and then each shank end is further rearwardly and thenforwardly curved, as shown and described, the object being to permit thebrushes to be brought closely together, so as to clean both sides of theteeth at once, and at the same time by reason of the described obliquearrangement of the brushes relative to the handle and the describedpeculiar curving of the shanks to prevent unpleasant contact between theshanks and the lips and mouth of the user.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A tooth-brush comprising a handle, oppositely-disposed substantiallyoblong brushes arranged in longitudinal planes, slightly oblique to thelongitudinal plane of the handle,

and means for connecting said brushes to one end of the handlecomprising yieldable arms each fastened at one end to the handle and atthe other end to one of the brushes, said arms being curved in oppositedirections to separate the same and both curved rearwardly in the samedirection from the.

handle and thence forwardly to their points of connection with thebrushes substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand, atFond du Lac, in the county of Fond du Lac and State of Wisconsin, in thepresence of two witnesses.

ALBERT HAUSSMANN. Witnesses:

A. H. FURSTNOW, HENRY B. Louis.
